Window security screens

Abstract

Security screens for windows and other openings may include a screen pattern generally conforming to a two-dimensional foam topology, such that solid segments outline a plurality of openings or cells. The solid segments may include circular arcs of varying length and radius, intersecting at 120-degree angles, in threes, at a plurality of vertices. Manufacturing methods may include simulation of a two-dimensional foam subject to certain constraints, such as a target range for the areas of cell openings.

These solutions enhance security, but tend to detract from the appearance of the building. Not only are the standard bars and grids imposing and unappealing, they also offer limited customization.

AI Technical Summary

Benefits of technology

The technical effect of the patent text is to provide an attractive, highly variable, and relatively low-cost security screen solution that does not detract from the appearance of the building or offer limited customization options. Existing solutions are bulky, often leaving large openings between bars, and reducing the sizes of these openings is costly. Therefore, there is a need for a new solution that addresses these issues.

Problems solved by technology

These solutions enhance security, but tend to detract from the appearance of the building.

Not only are the standard bars and grids imposing and unappealing, they also offer limited customization.

Furthermore, existing solutions are bulky and often leave large openings between bars.

Reduction of the sizes of these openings is costly, in terms of manufacturing cost and material usage.
